Sudfeld will mimic Brady's checks and "gyrations" at the line of scrimmage to give the Eagles the best possible look -- always a challenge against the Patriots, in part because their passing game includes a lot of conversion rules on routes, so the cards drawn by defensive coaches based on tape don't always match the play design.

"Sometimes, the defensive coaches don't see it as offensive coaches," Sudfeld said, "so they'll draw the exact line that (the Patriots) did, which looks like what they did on the field, but then sometimes, the route is changed based on the coverage, so it'll be like an out-route versus Cover 3, but if it's Cover 2, it's going to look like a corner. Then (in practice) it'll be Cover 2, and it'll be an out-route -- I'll be like, 'There's no way they run that into Cover 2.'"

With Carson Wentz injured, Sudfeld also will serve as the Eagles' No. 2 quarterback behind Nick Foles, meaning he's only one snap away from a Super Bowl appearance himself.
